Drestam answered that topic on the French part of the forum, please find the translation below :
I find us very transparent on this subject, even if indeed I answer it mainly on the Discord.
The reopening of Atreia is currently not planned. It is not enough to look at the situation at the moment, we must take into consideration what will happen when we lift the blockade. This is not an assumption: the queue problems will come back again.
We are working on a solution to fix these issues even with Atreia completely free to access and we will probably not open until we have this solution in place.
If you want to play with your friends, you can play on the Tahabata server. The latter is also very active and has no blocking for the creation of new characters. You can also, until tomorrow, take advantage of exclusive rewards by visiting Tahabata (link).
Hope I answered all your questions
Unfortunately it doesn't work like that. Atreia will never be full again. Historically playerbase is declining since launch and after first year you lose about 70-80% of launch player base. Two months from now you'll email people saying "Atreia is OPEN NOW!!!" but nobody will care about.
Keeping Atreia locked makes people like me to not start investing precious time in a server that was made in the mist of desperation. Been there done that with Lost Ark, I'll never do it again.
